推荐答案

听起来像您还没有准备好使用此Web服务器.它真的不需要用户名或密码吗?

Sounds like you haven''t set yourself up to use this web server. Does it really not need a username or password ?

u可以使用它.通过使用以下代码，我发送了邮件.
在这种情况下，我使用了Gmail帐户.

u can use this. by using the following code i sent mail.
In this case i used Gmail account.

MailMessage mail = new MailMessage();
mail.From = new MailAddress(textBoxFrom.Text);
mail.To.Add(textBoxTo.Text);
mail.Subject = textBoxSubj.Text;
mail.Body = textBoxBody.Text;
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);

smtp.EnableSsl = true;
smtp.Credentials = new  NetworkCredential("Your-Gmail-account", "gmail-password");
//Your-Gmail-account="[e-mail]" ,
//gmail-password="123456"

try
{
    smtp.Send(mail);
    lblStatusMsg.Text = "Message sent";
}
catch (SmtpException ex)
{
    MessageBox.Show(ex.Message, "Error: " + ex.Message, MessageBoxButtons.OK, MessageBoxIcon.Error);
}

好像您没有为电子邮件配置Web.Config文件，例如:

Looks like you have not configured the Web.Config file for Emails, like:

<configuration>
  <!-- Add the email settings to the <system.net> element -->
  <system.net>
    <mailSettings>
      <smtp>
        <network 

             host="relayServerHostname" 

             port="portNumber"

             userName="username"

             password="password" />
      </smtp>
    </mailSettings>
  </system.net>

  <system.web>
    ...
  </system.web>
</configuration>
